You can still get the vaccine even if you are already infected with HPV because there are so many subtypes of HPV and the HPV vaccine only targets a few of the HPV subtypes and does not cover them completely. Because there are many subtypes of HPV and the HPV vaccine also only targets a few of these subtypes and does not completely cover them, the HPV that is infected may not be the type contained in the vaccine, so you can still get the HPV vaccine even if you are infected with HPV. In addition to this, when receiving the HPV vaccine, it is recommended that you choose the HPV vaccine that suits you at the right age. Generally, if you are under 45 years of age, the vaccine is beneficial, but it is recommended that you get the vaccine before you are not sexually active, for better results. It should also be noted that even for those who have been vaccinated against HPV, regular cervical cancer screening is recommended in order to detect cervical cancer lesions in a timely manner.
